<p>An efficient ripple free wide-band single-phase unidirectional SAW transducer (10) is disclosed which requires only a single tuning circuit and a single matching circuit (44). The unidirectional transducer includes a pair of bidirectional transducers the first (20) of which is connected to a single-phase drive source (42) and the second (18) is connected to a resonant load (44) such that the second transducer acts as a reflecting transducer to cancel out waves traveling in one direction.</p> |
